As you walk through a neighborhood or park, you might not think much about the trees. But arborists, who are like doctors for these leafy beauties, are in charge of deciding what plants work best in a certain place. As an arborist you could work as an independent contractor, for a government agency, or with a private landscaping company. Your daily to-do list would include more than just spending time in nature checking trees' health, though that is a big part of the job. You might also be writing grants that would help fund future projects, managing contractors who are planting new trees, and looking at budgets to decide how money should be spent. This is a great career for someone who loves being outside but also wants to use leadership and communication skills to protect the health of trees and, ultimately, our planet.
